QRSS and Baudline
I have been dabbling with baudline for the last few days for displaying QRSS signals and now have become quite pleased with how it performs. It seems that most of the QRSS software is Windows based but baudline is a nice Linux tool that can be used quite well for QRSS work, so offering an alternative for Linux users.
Below is a full screenshot of the desktop of the Linux box that I have been using for QRSS work. On the right hand side of the screen are (top to bottom) the play deck, the input devices and the scroll control windows. These show my settings for the screen display, which may help anyone wanting to experiment with baudline (click on the image to see better detail). The sample rate in the input devices window are covered by the play deck, but it was 5510 Hz.
You can see VE1VDM was coming in strong around noon on 28th Dec. 2008. As I mentioned in my earlier post, this is a 350mW transmitter (yes, that is milliWatts, just over 1/3 Watt!).
If you want to see QRSS signals, but do not want to be bothered with the software and fine tuning required then there are some live grabbers that display signals from receiving stations around the world and updated at regular intervals when operational. One receiving station that has a grabber (that has a link to others) is ON5EX’s in Zevergem, Belgium.
